Webb23 mars 2024 · (i) Quantification of phloem and xylem area and cell wall thickness of sieve tubes and companion cells in leaf sheaths and stems of NIP, f6Cas3, and F6OE8 plants. Data are means ± SD ( n = 3 biological replicates; for each replicate, 15 cells from five individual sections per genotype were used for quantification). WebbThe stele (or vascular cylinder) is in the central region of the root, where the xylem and phloem develop. In dicot roots, the stele contains clusters of phloem arranged around the central xylem. Dicot steles contain an additional component, not present in monocot roots, called cambium. Dicot root steles do not contain pith. See it in 3D! Pericycle
